Wood Group Contract for Permanent Downhole Sensors by Shell

Wood Group Production Technology (WGPT), a subsidiary of John Wood Group PLC, has received a contract for its endurable permanent downhole sensors from Shell Exploration and Production Company (SEPCo) for subsea well installations in the Gulf of Mexico.

The $10 million contract continues a long-standing relationship between the companies, and is a testament to the reliability of WGPT's monitoring systems. Since 1993, WGPT has installed over 100 permanent downhole sensors for Shell in the Gulf of Mexico, the majority in deep water subsea wells. When Tahoe and Popeye, the first wells with the sensors, were worked over after seven and 10 years respectively, the sensors were still providing pressure and temperature data upon retrieval. Fifth-generation technology—the 25,000 psi quartz-based ROC™ downhole sensor—was installed at gauge setting depths of more than 20,000 feet for Shell's Princess field.

"Reliability of downhole equipment is critical for efficient, and profitable, field operations, particularly in deep water, and WGPT's permanent downhole sensors have enabled our clients to accumulate data vital for reservoir analysis and production optimization," stated David Blacklaw, general manager of Wood Group Production Technology. "We are pleased that SEPCo has chosen to continue using our highly reliable downhole monitoring systems."

Wood Group Production Technology has installed more than 600 permanent downhole sensor systems worldwide, more than half of which are subsea.

Wood Group is an international energy services company with $2.0bn sales, employing more than 13,000 people worldwide and operating in 34 countries. The Group has three businesses—Engineering & Production Facilities, Well Support, and Gas Turbine Services—providing a range of engineering, production support, maintenance management and industrial gas turbine overhaul and repair services to the oil & gas, and power generation industries worldwide.
